RAILROAD-SWITCH.

Specification of Letters Patent. Patented Aug. 4, 1914.

Application filed February 21 ,1914. Serial No 820,226.

To all whom it may concern Be it knownthat I, JOHN ORBIK, a citizen of the United States, residing at Hurley, in

the county of Iron and State of Wisconsin,

have invented certain new and useful Improvements in:Railroad-Switches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

and has for one of its objects the provision of means for yieldingly holding the switch points in either of their respective positions, and theiprovision of means for the automatic movement of the same sothat rolling stock of the road, may pass through the same when the switch is closed to the track upon which the rolling stock is traveling.

A further object of this invention is the tion,combination and arrangement of parts thereof as described in the following specifi; cation, defined in the appended claims and illustrated in the accompanying drawings, in which,

Figure 1 isca top plan view of the switch and its component operating parts constituting my invention and illustrating the same as it appears in operative position. Fig. 2 is a transverseview of the switch taken on line 2+2 of Fig. 1 andlooking in the direction of the arrows.

Like reference characters denote corre sponding'parts throughout the several views of the drawings in which 1 represents the usual ties upon which are mounted the main rails 2-2 and the switch rails 3-3. For maintaining the rails 2-2 and 3--3 in their normal parallel relation to each other and positioned between the alternate pairs of ties are tension: devices comprising the This inventionirelates to railroad switches turn buckles 5 havin screw threaded in the opposite ends thereof the oppositely extendmgrods 6 which rods are provided upon thcirfree ends with the upwardly turned hook members 7 for engaging the outer base and web of the respective rails.

I desire to here state, that in view of the lack of space, and for thesake of clearness, certain of the parts of the switch mechanism have been slightly exaggerated, however, in practical use, the parts are to be proportionately correct.

Connected to the ends of the switch rails 3 are the switch points 9, the points being connected together and retained in their respective predetermined relation to each other by the arrangement of the web blocks 11 secured to each of the opposing faces of the points 9 in any suitable and efficient manner, theweb blocks 11 being provided withapertured ears 12. The webblocks 11 are positioned at points between the remaining alternate pairs of ties and have connected thereto the transversely extending bars 13, which bars have provided upon the upper surface thereof the apertured cars 14 at points upon the bars 13 in order that the same may be pivotally connected to the cars 12 of the web blocks 11 through the means of the pivotal bolts or other suitable connections 15. a

pair of switch ties 10-10 spaced apart :in

the usual manner and between them there 1 1s positioned the foremost of the connecting bars 13. Upon the switchties10---10and beneath the respective rails and switch 1 points are the bearing plates 10 to provide anti-friction or smooth traveling surfaces for the switch points 9.

The cross bars 13 are each elongated and adapted to pass beneath the bases of the respective rails and to project for a distance beyond the outer sides of the rails,as shown at 16, the purposes of these extensions be- 2 ing for maintaining the switch pointsin strict VBI'tlCfll posltlon and to prevent the l The foremost wabbling or overturning 0f the tread SUI? faces of the switch points.

cross bar 13 has one of its ends elongated and gradually increasing in dimensions to provide the switch rod 17, which hascarranged upon the upper surface thereof and adjacent to but slightly removed from the outer side of the rail 3, the upwardlyiex .tending lug 18 through which and the rail 3 is adapted to extend the horizontal sliding pin 19 and surrounding the pin 19 and" between the lug 18 and'theopposing; face of the rail 3 is the compression spring 20..

fornorn ally bearing the lug 1.8 in an outg ward direction. Arranged upon each of the switch ties andat a point sufliciently remote from the track are the journals 22 secured tov the switch ties by suitable fastening means as I indicated at 23, and" rotatably mounted within-the journals 22 is the horizontal shaft 24 provided intermediate of its ends with the elongated crank portion 25. The shaft 24is further provided with the angu-l'arlydisposed switch lever 26 provided at the extremity thereof with the weighted head 27. Longitudinally arranged upon oneofthe switch ties l0 and at opposite points-to the axis of, the shaft 24 are the lugs 28 to provide locking means for the "switch. lever 26 when in either of its respective' positions. Transversel'y arranged within the switch rod 17 and-in proximity to the outerextremity thereof is elongated slot 30 through which, the crank of the shaft is designed to pass and travel therein,

the crank 25 be'ingyiel'dingly retained there} in the compression spring 31 arranged in the longitudinal bore 32 extending from the sljot 8Q outwardly to the end rod 17* and "retained therein by the screw threaded?- ad justing screw plug H The switch rod 17 is preferably formed in one piece of sufli'cient length and degree of flexibility to provide for the slight vertical movement of the out'er'end thereof occasioned the crank 25. However, the switch rod be formed in two parts and pivotally connected together at any point between the lug I8 the slide bar 37,111. So d sir d. 1 Arranged upon the crank 25 and at either i side of the switch rod 17: arev the apertured heads 35 of the rodsish, these rods extending longitudinally at each side of the: switch rod 17"in.the direction of the track and having their free'en'ds extending'through the ears verselyarranged'slot 39 for positioning one 36, of the slide bar 37 and retained se cured relation thereto h-ythe adjiustable nuts 38;. screwthreaded thereon. The slide bar 37 is adapted to pass through a secondtransof, itsifears 336 tut-either side of the switch basement the path of the rods 36, the

slot 391 being-somewhat restricted in length r to, that of the slot 3.0 andiar-rangedin proxlll hlliylllilfiletO but between the slotBO and the track For, inain-ta-ining: the: slide bar 3% normally against the end wall of the sllot 3-9;

. inthedireetiion of the track, and for also maintaining-E constant. opposed stress between the; crank, 25* and? the slidebar- 37 the compression springs 40 are provided, these springs surroundingtheprodsand hav ing their opposite ends bearingagainst the opposingfaces of the heads and the ears 36 respectively; The spring 31 and the springs; are positioned atthe opposite .sides of the crank 25 for yieldingly retainringthe crank at a point approximately interlnediate of the ends of the slot 80, the slotbe'in'g of suiiicientlength for preventing ,contact of the crank25 with either of the end walls thereof. The slot 39 is arranged for permitting. the. slide bar 37 to normally engage the end of the same nearest the: track but of sufiicient length in the opposite slide bar 37 with the outer wall of the slot- 39. The compression spring 20 and the C0111? ward the track, but these springs, however,

drawings to not require further detail d'e-' direction for preventing the contactof the pression spring co-act with'each other and; have: a tendency to force the" switch rod 17 in a'd'lrection outwardly from the track, while the compression spring 36 have a tendency to throw the bar 17' 'to- V are of a suitable degree of strength for equalizing the. opposing tendencies.

' The operation 'of'the switch is clearly ohvious from the foregoing'description and the construction sufficiently illustrated in the scription of the operation of the device. However it is deemed expedient to note that in the position of the switch points shown in- Fig. 1 should a train pass out of the switch onto the main track the stress exerted upon the switch point by the flanges hf the wheels of the rolling stock would obviously force the rails in the opposite direction against the action ofthe spring 20' and the spring .31,

whereupon after the passageaofthe rolling I stock the points would be returned totheir original position.

Should the points be. in

the opposite position the switch rod and points would be forced against the compression springs 36, the same also returning the switch rod points to its former position after the passage of the rolling stock.

Having thus fully deseribed my invention,

what I claim and desire to secure'by Letters- Patent-of the United States, is:
